Controller for remote-control toy airplane

Abstract

A controller for use in a remote control toy airplane is disclosed to include a booster circuit for boosting the voltage of the battery of the remote control toy airplane to the desired voltage level for the working of the motor of the remote control toy airplane, and an electronic speed-change control circuit for controlling output voltage and current from the battery to the motor of the remote control toy airplane subject to the nature of the wireless control signal received from a wireless receiver.

1 . A controller comprising a booster circuit and an electronic speed-change control circuit and used in a remote control toy airplane and electrically connected to a motor of said remote control toy airplane and adapted to control the operation of said motor subject to an external wireless control signal, wherein said booster circuit comprises a booster chip, a thyrister, a plurality of inductors, a plurality of capacitors and a resistor, and is electrically connected between a 2.4 V battery power supply of said remote control toy airplane and said motor for boosting 2.4 V battery power to 4.8 V for the working of said motor.  
   
   
       2 . The controller as claimed in  claim 1 , wherein said electronic speed-change control circuit comprises a CPU, a thyrister, a capacitor and a plurality of resistors, and is electrically connected between a wireless receiver and said motor for receiving a wireless control signal and controlling output voltage and current from said 2.4 V battery power supply to said motor subject to the nature of the received wireless control signal.
